Question

我正在接收广播片段，例如

 BroadcastReceiver br = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            // Log.e(TAG,"inside onReceive");
            if (intent.getAction().equalsIgnoreCase(
                    DATA_AVAILABLE))
                initFragments.run();
                }
     }

InitFragment是一个带代码的可运行的

dataBrowse = new SongListFragment();
                getSupportFragmentManager().beginTransaction()
                        ./*replace*/ add (R.id.container, dataBrowse ).commit();

除了手机锁定外，它始终完美无缺。为什么会这样？这个原因的解决方案是什么？
